But, very few somebody knows, since id card must be used when safe examination, so why is id card shown even when buying a ticket?

As we have learned, have the reason of tripartite face: One of, the sheet that buy a ticket must fill in when the passenger buys a ticket, fill on exact Id number, so that be expert at class abnormal or when occurrence accident, can know fundamental condition of the passenger through Id number; Secondly, people needs to fill in in daily life when him full name, often use a habit to use a word, appear easily to be the same as the situation with different word with the sound on Id that is to say; Thirdly, id has temporarily, 10 years, mix 20 years long-term 4 kinds, to the person of seldom use Id, notice its period of efficacy rarely, using likely inadvertently so expire certificate seizes the opportunity. If civil aviaton staff member does not examine identity document when carry out ticket, so 3 kinds of afore-mentioned situations cause a passenger possibly to not agree with or cannot embark on a journey because of the full name, and bona fide location cannot be searched when encountering contingency.
